bitbake/fetch: Respect forcefetch even when pulling from a mirror

When pulling from a premirror we would prefer a local tarball even when the
caller had specified the forcefetch parameter.
Add an extra parameter 'force' to try_mirrors, defaulting to False. If set
the mirrors will be tested even if the file exists locally.
